Feb. 9, 1937. o. KRAMER FURNITURE WEB SUSPENSION PLATE Filed Sept. 24, 1955 //1///E/V7'0/ 0 77-0 4. iFe/v/vf/e. XWfi'TK Patented Feb. 9, 1937 UNITED STATES PATENT OFFICE 17 Claims.

My invention relates generally to the seats of chairs and like articles of furniture and more particularly to a connection and suspension plate for the strips of webbing that are positioned in the seat frame.

The principal objects of my invention are, to generally improve upon and simplify the construction of the webbing attaching and suspension means and to provide a web attaching and suspending device that is highly effective in securely holding the webbing that is connected to the device so that it cannot possibly sag as a result of slipping through the suspension means.

A further object of my invention is, to provide a furniture web suspension that will effectively secure the ends of sections of webbing of predetermined and uniform lengths, thus producing a structure of uniform tension and balanced resiliency so that the applied weights and strains are uniformly distributed throughout the entire webbed structure and transmitted through the attaching means to the frame that surrounds the webbing.

A further object of my invention is, to provide a web suspension comprising two cooperating plates of metal or the like which when properly assembled, efiectively clamp the webbing that is applied to the plates and one of said plates carrying a pointed projection that passes through the center of the engaged webbing to materially assist in securing the same to the plates and said pointed projection having an aperture that coincides with an aperture in the other plate to provide a point of connection for one end of the helical spring that connects the web engaging plates with the seat frame of the furniture.

A further object of my invention is, to provide a furniture web suspension that may be easily and quickly applied to the web and likewise easily and quickly connected by the helical springs to the furniture seat frame.

With the foregoing and other objects in view my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:

Figs. 1 and 2 are perspective views of the cooperating plates that are applied to the strips of webbing.

Fig. 3 is a plan view of the end of a piece of webbing with the plates applied thereto and also showing said plates connected to a seat frame by a helical spring and a member that is driven intothe frame,

Fig. 4 is a vertical section taken on the line 44 of Fig. 3.

Fig. 5 is a plan view of a modified form of the suspension plate.

Fig. 6 is a cross-section taken on the line 6-45 of Fig. 5, and showing the position. of the web that passes through the slots in said plate.

Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, In designates a substantially rectangular plate of metal provided with a longitudinally disposed slot or opening ll.

That portion of the edge of the metal at the side of the slot or opening that is adjacent the center of the plate is bent downwardly to provide an inclined lip or flange l2.

Formed through the plate l0, between the side of the opening that is provided with the flange l2 and the adjacent edge of said plate, is a longitudinally disposed slot l3.

Formed through that portion of plate ID on the opposite side of the portion that is provided with slot 13, are apertures l4, one of which is located midway between the ends of the plate.

The cooperating web engaging plate is illustrated in Fig. 2 and this member comprises a narrow plate l5 of metal, the length of which is practically the same as plate It).

The material along one edge of plate i5 is bent downwardly at right angles to form a depending lip or flange l6 and the ends thereof terminate inwardly from the ends of plate [5 in order that said lip or flange I6 may readily project downwardly through the opening H.

Formed integral with the edge of plate l5, opposite the depending lip or flange I6, is an outwardly projecting pointed prong ll that is shaped somewhat similar to a spear head and said prong occupies a plane slightly below the plane occupied by the plate [5. This arrangement is necessary in order to permit the prong to lie immediately beneath the plate I when plate I is applied thereto and the two plates are engaged on the webbing.

Formed through the prong H is an aperture l8, which when the two plates are properly assembled, coincides with the central one of the apertures I4 in plate I0.

In applying the cooperating attaching and suspension plates to a strip of webbing such as W, a portion of said webbing at the end thereof, is folded double and said doubled end is inserted from the top downwardly through slot l3 and the end of the folded portion is then brought upwardly from the bottom through opening H.

Plate i5 is now inserted lengthwise through that portion of the folded webbing that projects upwardly through opening I l and when said plate is positioned so that its ends project equidistant from the edges of the webbing, the prong I1 is forced through the center of the webbing at the fold line thereof.

Thus plate It is positioned between the two layers of the folded portion of the webbing with the prong projecting from the folded end of the webbing.

Plate l5 with the webbing passing therearound is then turned slightly and the projecting prong i7 is moved downwardly through opening I l until the ends of plate I 5, beyond flange l6, overlie the ends of plate l0, beyond the ends of opening H.

Plate i5 is now slightly rotated so as to position the prong ll immediately beneath that portionof the plate it in which the central one of the apertures M is formed, thus aligning the said central aperture with the aperture l8 and when so positioned the ends of plate l5 beyond flange l6, overlie the ends of plate iii and depending flange it occupies a position immediately adjacent and parallel with the inclined flange l2.

The body of the webbing beyond the plates is now pulled away from said plates, thereby pulling plate I 5 so that depending flange i6 moves toward inclined plate E2 to firmly grip the interposed portion of the webbing and the end of a conventional helical spring S is now inserted through the central one of the apertures I i and the aperture 58 in prong 57.

The outer end of the helical spring is engaged in an aperture that is formed in a prong shaped plate E9, the latter being driven into the seat frame.

Formed in the sides of the prong l 9, are notches 20 and after the prong has been driven into the seat frame, it is anchored therein by means of nails 2! that are driven downwardly through the frame member and through the notches 2!] (see Fi 3).

Thus when the webbing and cooperating plates are properly assembled, the doubled end of the webbing passes through slot l3 and around plate l5 with one thickness of the webbing effectively clamped between the depending flange IS on plate l5 and the inclined flange i2 on plate it.

Inasmuch as furniture webbing is generally loosely woven, the prong ll may be passed through the webbing without breaking the yarn or cords from which it is woven and thus the webbing is very securely attached to the cooperating plates and slack or sag in the webbing due to slipping or tearing is effectively prevented.

Inasmuch as the prong ll underlies a portion of plate it, a double thickness of metal is provided for the attachment of the helical spring and such construction produces double strength and security at the point of greatest strains and friction between the webbed structure and the seat frame.

The prong on the plate or bar l5 may be in serted through the webbing at predetermined points and as the doubled portions of the web are folded over the plate, said plate with the prong projecting through the Webbing, may be threaded through the slots l3 and i2 and positioned on top of plate 90 directly over slot ll so that the depending flange It on plate cooperates with flange or lip l2 on plate ill in gripping and securing the webbing to the cooperating plates.

The advantage of this construction is to enable the plates to be applied to the web at predetermined lengths so as to produce the desired tension and to make it possible to follow prescribed patterns in making a multiplicity of foundations for a known type of furniture frame.

In Figs. 5 and 6 I have shown a modified construction wherein a plate 22 is provided with three parallel slots 23, 24 and 25 with a lip or flange 26 depending along one edge of the intermediate slot 24.

Where such a plate is used, the webbing is threaded downwardly through slot 25, thence beneath flange 26 and upwardly through slot 24, thence downwardly through slot 23, thence beneath that portion of the webbing below flange 26 and thence upwardly through slot 25 underneath the overlying portion of the web that passes downwardly through said last mentioned slot. This construction involves only one plate and may be advantageously employed for firmly securing the webbing to the seat frames of certain types of furniture.

Thus it will be seen that I have provided a furniture web connection and suspension that is relatively simple in construction, inexpensive of manufacture, easily and quickly applied to the webbing and effectively holding the latter against strains and stresses that would otherwise result in sagging and slipping of the webbing.

It will be understood that minor changes in the size, form, and construction of the various parts of my improved furniture web suspension may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claims.
